Simple commands for Linux developers
As an example scenario, we are going to pretend we are developing a LAMP (Linux, Apache, MariaDB and PHP) application on single machine running Red Hat Enterprise Linux 7. As a first step, we’re going to install Apache, PHP and MariaDB (the drop-in replacement for MySQL that’s shipped with Red Hat Enterprise Linux 7), and start the appropriate services:
|
# yum -y install httpd mariadb-server php-mysql php
|
Installs the correct packages to start developing a LAMP application: the Apache webserver,
the base packages for PHP, and a MariaDB server, including MySQL bindings for PHP.
|
|
$ systemctl status httpd
|
Show information about httpd, including process ID, child processes,
time since startup, what man pages are available, the most recent log messages, and more.
|
|
# systemctl start httpd mariadb
|
Start the httpd and mariadb services. Instead of ‘start’, you can
also use stop or restart, for obvious use cases
|
|
# systemctl enable httpd mariadb
|
Enable the httpd and mariadb services to start at next boot.
You can also use disable, mask or unmask.
